How can I save this plant of mine?
I bought it a month ago and repotted before buying. I am watering the plants when top of the soil feels dry. There is indirect sun for around 3 hrs a day. It's on terrace balcony of flat.

You need potting soil, and more sun. That clay will compact, and will not allow for nutrient uptake or air exchange.
Simply change the soil to a light potting soil, and you will see a totally different plant within a few weeks. You may also want to add a horticultural light for a few hours if the condition continues to decline after repotting into a light soil mix.
